If you have an alt with any of these levels, please feel free to contribute. It would help us a lot! You can literally just copy paste the numbers below and just add exp requirements to the right side.

did lvl 69 thru 96 today
all numbers matched w/ cookie's even the skipped ones lol
there is a HUGE jump right before you go to the pyramid because they combined 2 of the tasks (a while back) so they complete together... that is level 77 through lvl 81 for me..

I should note the chat only said i got 2x 10HP and 5 SP (during that large jump) but by looking at my red and blue bar numbers I actually got +40HP and +20SP which is correct considering I went up 4 levels at that point.

Long story short, levels 1 to 150 are all giving +10 HP and +5 SP. The reason why some of the data shows more than +10 HP has to do with bare handed fighting skill. Storyline also levels your bare handed fighting and the skill itself is giving some HP. So you have to be careful when distinguishing how much HP you gained.
